I agree that you'd go round the twist if you tried to cater to every individuals requirements.

I didn't mean tapers or tuned lengths or such.

I just remembered reading somewhere that the sudden curve of the std header as it leaves the head was a restricting factor and some performance pipes improved this bend for beter flow.

Just thought it would be better to copy this if we could.

Cheers, Andy.
Hi Andy,

Sorry, my previous post was in general, not a direct reply to your post!

I think the bend as the tube leaves the head would have to be less sharp anyway to accommodate the larger diameter, which in itself would flow better than the standard pipes- you couldn't bend a 1.5" tube to the same radius as you could a 1" tube, for example, because it would just crease.

I'll have a word with the exhaust place after the holidays are out of the way and see what kind of prices they could do :D

This is very true any gas movement is easier to move over a larger radius rather than a tight radius curve.

Hi

I'd like a 2-1-2 system :D

So I am right in thinking that link pipes would would have to be me made and bolted on those headers followed by which ever cans one wants? what diameter are the headers? Could the exhaust place you're dealing with modifiy my link pipes to fit those?

I know, too many questions, sorry :lol:

Cheers
A

And so it begins... :lol:

The systems would be stand-alone and not interchangeable with the standard parts, sorry, it's just too much hassle for me and the fellas who'd be making the parts and it'd probably cost as much to modify a pair of standard links as it would just to make up a couple of new ones that's they'd already have the jig for, plus they'll be held together with springs not clamps.

I'd imagine the headers could be the same for both systems, but there'd be (obviously) different collectors and different links. They might be able to do it so that the right side link on the 2-1-2 is the same as the one on the 2-1 system, which would be useful as people could then buy a 2-1-2 collector and left side link if they wanted the choice of either system.

So, to clarify and draw a line under the whole 'choice' thing, in short, no. There will be two systems, both stand-alone and non-compatible with the standard parts (unless by some fluke they end up being, but it won't be through design!)

They'll be supplied minus cans, you will need to provide your own 2" cans (to keep the costs down and also because it'd be a nightmare trying to supply every different flavour of can). I'll get the systems made up using round race cans, so that I know they'll fit, and there'll be a degree of flexibility meaning you can use oval or whatever you fancy or have lying around.

Right, that said, should I go ahead and make a start on this, bearing in mind that you will need to buy a complete system and not just parts of it?

Will be intersted in two into 1 into 2, if cost is OK, bearing in mind repro Over system going for 1000 euros.

any chance of doing a large diameter 2 into 4 into 6 into 4 and back into 2 system made from zinc coated stainless unobtanium with hexagonal stubby carbon fibre cans plus removeable baffles?

I can pay up to 50 quid?

"Re: Big bore headers available soon"

So, will these be more like the MAB/Over 42-43mm-ish inner diameter?
If so i´m interested!

Hey Kayla would you like to borrow my set of Over pipework, with the view to making some `sensibly` priced copies?

That's a very kind offer, but no thank you :) If I take a bare rolling chassis in to them I can explain that I would like the two systems to be made on the same jig (so the parts are interchangeable) and they haven't got to worry about making a copy of something, and I don't get my bum sued off for breach of copyright! :D

KW- if the standard headers are 38mm OD (I think), these will be the next size up which is around 43-44mm OD (around 42mm ID).

Hi Kayla

Understand the limitations etc. I think that would work for me, you've got a PM. :wink:

42mm ID sounds good, i actually liked the power delivery on the MAB better than akra...

Define 'realistic' :lol:

I spoke to them this morning, and the 2-1 will be around £275 but he needs to see the bike before he can give me an actual price for the 2-1-2. Ultimately, if you're willing to pay for someone's time and skill and the fact they're made in the UK, by hand (not the bends, obviously!), the prices will be 'realistic' ;)

This isn't a once in a lifetime, buy it now or never thing. I'll be paying to have a couple of each type made up initially so it's worth their while to make a couple of jigs up and once they're done, they'll be made per order with (usually) a two week turnaround :D
